Unable to compile spring boot project with java and scala using maven - java

I am trying to set up application using java,scala and spring boot. I have set up pom.xml. The code is running fine in intellij and I am able to run application successfully. But when i use mvn clean install , my project is not compiling.Its giving error as cannot find symbol for the scala class.
I have followed (this blog)
I am attaching below dependency and plugin section of pom.xml
I have tried various solutions and tried to move the order of the execution of spring boot build plugin, but un-successful

I figured it out . The compile goal for the source should be associated with phase -> process-resources and testCompile goal should be associated with phase -> process-test-resources. Below is the snippet
<executions>
<execution>
<id>compile-scala</id>
<phase>process-resources</phase>
<goals>
<goal>add-source</goal>

QueryDSL Q classes are generated in target folder but cannot be imported in other spring boot modules

I have multi module project (spring boot) and I configured QueryDSL in dao module it's working perfectly and it generated all Q classes.
But when I import this module in service module and I import a Q class in the IDE (Intellij) it does not show any error but when running mvn clean install I get an error that the class is unresolved.
Unresolved reference: QRole
Here is the code for pom (dao module) :

The solution is:
Right-click the project folder
Select Maven
Select Generate Sources And Update Folders
Then, Intellij automatically imports generated sources to the project.

IntelliJ no longer recognises JavaFX components

I managed to break my old MacBook and moved over to a new one. Upon re-installing IntelliJ and retrieving a Kotlin TornafoFX project from Git, the IDE no longer recognises any JavaFX components. I added JavaFX to the POM, which now looks like this:

I also get an error like this reported by the IDE:
java.lang.NoClassDefFoundError: javafx/scene/paint/Color
This did not happen on my old machine and JavaFX was not even required in the POM. Can anyone help me?

Turns out I had to revert to JDK1.8. Not gonna question why...

IntelliJ Idea when testing multiple modules at once only artifacts from one module are included

I have a project which uses Maven with 3 modules: a parent one, core, and addon. Core has the same artifacts as parent, but addon has an additional one. When I run tests for addon only everything works okay. The problem occurs when I test both modules at once. The tests act as if the addon module didn't have that additional artifact which, causes tests fails. Again, this only occurs when I test both modules at once. Below you can find my configuration.

Annotation processing with kotlin-maven-plugin

So i have maven project with 2 modules.
Root pom.xml looks like this:
<project xmlns="http://maven.apache.org/POM/4.0.0"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xsi:schemaLocation="http://maven.apache.org/POM/4.0.0 http://maven.apache.org/xsd/maven-4.0.0.xsd">

Now everything works fine only if i manually create javax.annotation.processing.Processor file in resources directory.
That means that auto-service is not working and the question is: how do i make it work?
Also i tried to make the same project with java and it works. So i think that the problem is in kotlin-maven-plugin.
Source code of the project can be found here

auto-service is using annotation processor too so you have to add into your kotlin-maven-plugin (before compile section) this:
<execution>
<id>kapt</id>
<goals>
<goal>kapt</goal>
</goals>
<configuration>
<sourceDirs>
<sourceDir>src/main/kotlin</sourceDir>
<sourceDir>src/main/java</sourceDir>
</sourceDirs>
<annotationProcessorPaths>
<!-- Specify your annotation processors here. -->
<annotationProcessorPath>
<groupId>com.google.auto.service</groupId>
<artifactId>auto-service</artifactId>
<version>1.0-rc4</version>
</annotationProcessorPath>
</annotationProcessorPaths>
</configuration>
</execution>

Spring toolsuite shows error on <execution> for maven-jaxb2-plugin

I am using Spring Tool Suite version 3.7.0.RELEASE and I'm trying out an import of a WSDL offered by Amazon. The import succeeds, but Eclipse gives an error message on the tag.

When hovering over this tag, I get the following error message:

I was able to fix this by putting my <plugins> inside of a <pluginManagement> tag. Somehow this makes it different for maven and it actually picks up the correct information.

Putting it in <pluginManagement> means it won't get executed. Plugin version 0.13.2 fixes this issue.
